A vehicular suspension system incorporates, at each wheel, a liquid spring which internally utilizes a compressible liquid to generate spring and damping forces that yieldingly resist vertical wheel deflection relative to the vehicle frame. The liquid spring includes a dual piston assembly which divides a main cylinder into bounce and rebound chambers. A rotary metering valve is interposed between the bounce and rebound chambers for controlling the flow of compressible liquid from one chamber to the other during bounce and rebound. The dual piston assembly includes a tubular piston having a modulation chamber coupled in flow communication with the bounce chamber. The spring and damping characteristics of each liquid spring are computer adjusted during vehicle operation by modulating the bounce chamber pressure in response to sensed variations in various liquid spring and vehicle operating parameters.
